Effect of Zn, Mn, Fe sprays on growth of gerbera under poly house conditions

Abstract

Gerbera is one of the most imperative commercial cut flower. The growth parameters of gerbera are directly dependent on the balanced application of macro and micronutrients. In the present study, foliar application of micronutrients was done after 30, 60, 90 DAP. Foliar application of ZnSO4 (0.2%) + MnSO4 (0.2%) + FeSO4 (0.1%), produced significantly maximum plant height (44.87 cm), Plant spread (45.20 cm), Number of leaves per plant (16.93), Length of leaf (32.14 cm) as well as Number of suckers per plant and width of leaf (13.69 cm) were significantly increased as a result of foliar application of ZnSO4 (0.4%) + MnSO4 (0.4%) + FeSO4 (0.3%), compared to the control treatment.
